Title: Improvements in or relating to change speed gear mechanisms
IPC: F16D43/28
Filed: 1935-12-10
Abstract: 471,852. Change - speed gearing; clutches. POTTS, H. E. (Monopower Corporation) Dec. 10, 1935, No. 13516/37. Divided out of 471,797, under which a Specification was laid open to inspection under Sect. 91 of the Acts, June 11, 1936. Drawings to Specification. [Class 80 (ii)] The subject-matter is the same as that of Specification 471,797, but the claim is directed to the fact that one of the driving plates of the second-speed multi-plate clutch is fixed to or capable of only a limited angular movement relative to the driving member of the one-way clutch through which the plate-clutch is driven, the remaining driving plates being fixed to the driven member of the one-way clutch. Thus, it is pointed out, when the plate-clutch is disengaged, positive rotation of its driving and driven plates at different speeds is avoided, whilst, when the plate-clutch is engaged, the clutching action of the single plate is available for locking the one-way clutch to transmit engine-braking torque. Specification 455,083 also is referred to.

Title: Improvements in or relating to sealing packings
IPC: F16J15/32
Filed: 1959-04-22
Abstract: 875,620. Stuffing-box substitutes; pistons. REGIE NATIONALE DES USINES RENAULT. April 22, 1959 [May 19, 1958], No. 13781/59. Addition to 853,996. Classes 122 (1) and 122 (5). A packing for use between a piston or piston rod and cylinder comprises a resilient operative portion 1 which is secured, such as by vulcanization, to an annular metal-reinforcing member 2 and consists of a sleeve portion having at one side of the member 2 a radial extension provided with a tapered sealing lip 9 stressed for relative sliding engagement with the cylinder, piston or piston rod as the case may be, the thickness of the sleeve portion being less than the average thickness of the lip and the contact sealing surface of the lip and adjacent portion of the radial extension being arranged to bear continuously against the members with which they coact over the entire axial length of the surface. As shown in Fig. 3, the radial extension has two tapered lips 8, 9 divergent in their free state so as to be stressed when in use. In order to prevent the resilient material of the packing, when subjected to fluid pressure in the direction of the arrow 51, from being compressed towards the lip 9 and thereby increasing the frictional resistance of the lip, the face 55 of the member 2 is formed as a frusto-conical plane surface; for the same reason, the thickness of the sleeve portion is reduced at its end 57, a similar reduction in thickness being made at the end 58 to reinforce the connection between the sleeve portion and member 2. A single annular groove 59 in the sleeve portion serves as a reservoir for lubricant. When applied on a single-acting piston, the resilient member 1 is provided with an enlarged extension 18, Fig. 6, to engage in a corresponding groove in the piston, and a buffer projection 22 may be provided between the lips 8, 9. For double-acting pistons, the radial extension may extend inwardly on both sides of the support member as shown in Fig. 9. In other constructions, the support member is of L-shape and two packing devices of the form described may be disposed side by side in a cylinder or on a piston.

Title: Wire-drawing bench
IPC: B21C1/12
Filed: 1948-05-22
Abstract: 645,231. Drawing wire. HENDERSON, W. S. May 22, 1948, No. 13929. [Class 83 (iv)] A wire-drawing bench comprises a drum around which the wire is led, a jockey pulley, a gear-box which is infinitely variable between its extreme ranges by rotation of a control shaft, means connecting the output shaft of the gearbox to the drum, means connecting the jockey pulley to the control shaft and means for varying the initial angular position of the control shaft. The Figure shows one stage of a continuous wire drawing machine. The wire 1 is drawn through a die 2 by a driven drum 3, passes round a vertically movable weighted jockey pulley 5 and over a guide pulley 9 to the next drawing die 10. Drum 3 is driven by a belt 13 from a continuously variable speed gear which is adjusted by means of cables 17 and 18 secured to and passing in opposite directions around, a pulley 15 on a shaft 16. Cable 17 passes round a guide pulley 20, beneath a pulley 22 mounted on a rod 6 depending from the jockey pulley 5 and is then anchored to the upper end 24 of a turnbuckle device. The other cable 18 passes in the other direction round the pulley 22 and is secured to the lower end 25 of the turnbuckle. Shock-absorbing springs 29 and 30 are included in the cables 17 and 18. A nut 28 on the turnbuckle serves to adjust the initial tension in the cables, while the tension at which the pulley 5 floats is adjusted by altering the position of the turnbuckle device as a whole, by turning a hand wheel 27 and thereby rotating the gear-operating pulley 15. Stops 31 and 32 limit the extent of movement of the rod 6 through a bearing 7. Specification 374,852, [Group XXIV], is referred to in the Provisional Specification.

Title: Improvements in or relating to photoelectric sorters
IPC: B07C5/342
Filed: 1949-05-25
Abstract: 662,685. Sorting photo-electrically STEVENS, A. H. (Electric Sorting Machine Co.). May 25, 1949, No. 13967/49. Class 40 (iii). Images of articles to be sorted photo-electrically are projected into a plane between the article and the photo-cell and a scanning device in this plane exposes the cell to successive portions of the image. As shown, almonds for example are lifted one at a time from a supply 34 by suction tubes 13 carried on the periphery of a wheel 12. Part of the periphery of this wheel passes through an illuminated chamber 14 in which the almond is compared with the background of a replaceable plate 33 (Fig. 3). Light reflected from the face 31 of the beam passes through a lens system 15 (which may be an achromatic combination) and is brought to a focus at the optical centre of a further lens combination 17, 18. The purpose of this combination is to defocus the light from the bean on to the photo-cell so that irregularities of photo-cell sensitivity are ineffective. At the optical centre of this lens combination is situated a scanning plate 16 having near its edge holes 44 so that as the almond is traversed horizontally the hole examines successive vertical bands, the disc rotating at such a speed that the bands overlap. To prevent the cell receiving pulses as a result of receiving light first from one aperture and then two, bars 47, 48 are provided which are relatively angularly adjustable, the top bar being friction held and the lower screw adjusted so that as one aperture enters the space between the bars the other leaves it and the photo-cell is always receiving light from an area equal to that of one aperture. Almonds in which one spot differs in colour from the rest or which differ in colour from the background are rejected by a pusher 21 into a trough 23. Good almonds enter a trough 25. The scanning disc may be replaced by a reciprocating plate or a mirror drum, Figs. 13 and 14 (not shown). Examples of suitable ejector control mechanism are given in U.S.A.

Abstract: 525,807. Tin sulphides. A. B. INDUSTRIMETODER. May 10, 1939, No. 13978. Convention date, May 16, 1938. [Class 1 (iii)] Low-grade tin ores, slags &c. are mixed with silica and with pyrites or other sulphides if not already present, and smelted in a shaft furnace into the lower part of which air is blown. The sulphide content of the charge and the air supply are so regulated that the pyrites are oxidized and the tin is volatilized in the form of sulphides. A small amount of coke may be added to the charge if necessary. The slag withdrawn from the furnace may also be treated with hydrogen sulphide with or without reducing materials to recover tin from it in the form of sulphides. Ores rich in iron oxide may be subjected to a preliminary reduction to convert this into magnetite which is magnetically separated before the ore is smelted.

Title: Improvements in the treatment of cellulose fibres
Inventor: CAMERON WALTER GLEN
IPC: D01F11/02
Filed: 1960-04-22
Abstract: The water imbibition, of cellulose fibres, e.g. cotton and regenerated cellulose woven fabrics, is reduced and their crease resistance and dimensional stability are improved by impregnating them with an aqueous solution containing formaldehyde and zinc nitrate in which the molecular ratio of zinc nitrate to formaldehyde is less than 1 to 14, e.g. from 1:26 to 1:40, and drying and heating them to effect reaction between the cellulose fibres and formaldehyde.  The zinc nitrate is preferably used in the form of its hexahydrate, Zn (No3)2 6H2O. The pH value of the aqueous solution is preferably adjusted to between 4 and 7 by the addition of formic or acetic acid or aqueous caustic soda solution.  The fibres preferably carry 0,5-8% by weight of formaldehyde at the time of drying. Reaction between the fibres and the formaldehyde may be effected by heating to 130 DEG -170 DEG C.  The treating solution may also contain other finishing agents, e.g. softening agents, lubricants, antistatic agents and crease resisting compositions, such as urea formaldehyde precondensates, polyvinyl alcohol and polythene. Specification 930,132 is referred to.

An airborne vehicle is maintained on a set course in a verticle plane towards a target, by continuously measuring the cosine of the angleof-sight, i.e. the ratio of the altitude to slantrange. The altitude is measured by a radio altimeter and the slant-range as the second integral of the acceleration along the line of sight (g cos 0). N‹ and R‹ cos # are compared in a differential coupled to an actuator controlling the elevators on the vehicle. In one embodiment, misalignment between the actual and computed line of sight may be corrected by an observer in an accompanying aircraft utilizing a television camera carried by the vehicle. If visual contact is lost the vehicle continues to fly on the last set angle-of-sight, Fig. 2 (not shown). In another embodiment a conventional radar equipment gives direct measurement of the slant-range and corrects the computed range, and if radar contact is lost the vehicle flies on the last set angle-ofsight, Fig. 2 (not shown).

Title: Improvements in or relating to bag valving and sleeving machines
IPC: B31B19/84
Filed: 1955-05-20
Abstract: 781,623. Valve bags. INTERNATIONAL PAPER CO. May 20, 1955 [Nov. 26, 1954] No. 14574/55. Class 94(2). A machine folds the valve corner of a gusseted paper &c. bag to form a valve and inserts a valve sleeve which it forms from a web, the valve being finally folded about the sleeve. Each bag A, Fig. 16, is placed against stops 155, 156 with fingers 20, Figs. 3, 16, 18, disposed within the gusset adjacent the valve corner and plates 21 on either side of the bag. The plates 21 first swing inwards to clamp the bag between them and then both they and the fingers 20 pivot about a vertical axis through 90 degrees and fold the valve corner to the form shown in Fig. 7. Plates 52 swing upwards about a shaft 49 to assist in maintaining the valve flat during .sleeving. The sleeves 84 are cut from a web which passes over a guide roller, 87 to draw rolls on shafts, 91, 92, and to cutting and creasing rolls, the latter producing a transverse crease adjacent the trailing edge of the sleeve. The sleeves then pass to glue means 103 for applying adhesive to the trailing edge. The prepared sleeve blanks are fed into grippers 117 on a continuously operating chain conveyer 112 and are carried to transfer devices for inserting the trailing edge between the valve lip and the bag sides. The transfer devices 136, Figs. 18, 24, 28, 29, consist each of an arm 137 rotating continuously about a shaft 132 and having clamping plates 148, 149 which grip a sleeve 84 between them for removing it from the conveyer 112. Each arm carries a tucking plate 153 which enters between the valve lip and bag sides to guide in the trailing edge, Fig. 28, and then pivots backwards on its arm at such speed as not to interfere with the deposited sleeve. At the same time the nose of the plate 149 of each device, presses the outer portion of the sleeve against the valve. A vertical folder 71, Figs. 18, 29, centrally placed in respect of the sleeve 84, is swung upwards on an arm 69 by a rack and pinion 63, 68. The folder is projected from its carrier plate 70 by an abutment 75 on a control wire 74 engaging a part of the machine frame, and folds the sleeve to the form shown in Figs. 9, 29. The plates 21 again fold inwards to clamp the valve and sleeve and consolidate the fold. The bag is filled and closed elsewhere in known manner, the closure being as in Fig. 1. If desired the sleeves may be longitudinally creased by a wheel 157, Fig. 16, co-operating with the roller 87. Reference has been directed by the Comptroller to Specification 598,461.

Abstract: 617,597. Making nuts. TRIPP, C. D. June 8, 1945, No. 14603. Convention date, July 28, 1944. [Classes 83 (ii) and 83 (iv)] [Also in Group XXV] Forging-machines ; dies.-Nut blanks with locking tongues 26, Fig. 4, have these tongues bent, to cause the threads on them to be distorted from the pitch of the main thread of the nut, axially radially and by varying the helix angle. The deformation is effected by a die 33, Fig. 6, having a threaded shank to screw into a ram, a flange 55 with opposed flats, and a concentric annular part 57 formed with one or more inwardly and axially extending crests 58 by grinding surfaces 59 to an angle of about 10 degrees to a horizontal plane passing through the crests. A modified form of nut blank is produced in a forging- machine to the shape shown in Fig. 9. In subsequent stages the lugs 62 are bent or rolled over to the position shown in dotted lines in Fig. 11. A combined reamer and tap is then entered into the blank from the face 67 to tap both the main body and the edges of the lugs. Finally the lugs are further bent to the position shown in full lines to distort the thread from the true lead position as described above. Specification 1649/03, [Class 89], and U.S.A. Specifications 2,320,785, and 2,352,668 are referred to. The Specification as open to inspection under Sect. 91 describes a press in which the nut 28, Fig. 13 (Cancelled), is supported on a bed 35 and the die is brought down by an eccentric operating a yoke (not shown) connected to the ram cylinder 37 sliding in guides 38 in the frame. The cylinder contains liquid above the piston 43 and a port 45 admits air above the liquid from a supply at 51 through a non- return valve 48 controlling the minimum pressure, a loaded exhaust valve 49 determining the maximum pressure. A predetermined maximum pressure is thus applied to the nut independently of the stroke of the press. This subject-matter does not appear in the Specification as accepted.
